"Lock system failure"

I get a "Lock System Failure" alarm from the SID when I accelerate and the car auto-locks all of the doors. It seems to be the rear drivers side lock that is the culprit. Plus when I lock the car using the remote it doesn't always honk like it should. When this occurs and I try to unlock the car with the remote the rear drivers side lock does not unlock. Any advice?

I have a drivers door that wont lock, unless that is I open the boot with the remote, then manually close it and lock the car again. The drivers door also has an imtermittent fault with locking. It seems to be more consistent now and sometimes gives a lock system failure note on the SID.I have a drivers door that wont lock, unless that is I open the boot with the remote, then manually close it and lock the car again.

You must have a "After Market Alarm" or something similar. The factory Auto door lock system doesn't lock the doors until the vehicle reaches 18 mph approximately.
So what I am saying is the Add-On Door Lock/Alarm System is malfunctioning - however some of those aftermarket systems can be programmed to lock doors with the engine running and Driver's door closed (they assume you will be sitting in the driver's seat at that time) It varies depending on which manufacturer built the system. I have seen on some of those systems they provide a small loopwire on the Module that can be cut to disable the Auto Door Lock feature - you might need the install manual to know which one.

The folk there are very helpful and 'parts department' will fax you a copy of the door lock electrics if you need it, although you will have to promise to buy parts from them.....service parts, oil filters, etc .

battery of car is zapped of energy...not sure if alarm system to blame, after driving it for a few minutes..clock and radio display lights turn off, horn can barely be heard...sometimes, motor shuts down completely. have had to put in 2 new batteries in just a matter of 2 months?...any idea what this may be?

When the armed Vehicle Theft Security System (VTSS) senses that the battery has been disconnected and reconnected, it enters its power-up mode. In the power-up mode the alarm system remains armed following a battery failure or disconnect. If the VTSS was armed prior to a battery disconnect or failure, the system will have to be actively or passively disarmed after the battery is reconnected.
The alarm can be disarmed by locking the vehicle and turning the drivers door lock to the lock (arm) position. Wait a few minutes then unlock (disarm) the drivers door and the vehicle should start.
If the VTSS has been disabled in the high-line Central Timer Module (CTM), the VTSS feature must be re-enabled using the Chrysler DRB scan tool. The clicking you heard was probably from the CTM located behind the glove box.

If your car has an alarm with a separate remote, it is a separate system and it is probably self-arming. When you lock the doors with the key central lock, the alarm gets armed by the RAV4 being OFF and the door locking action. When you unlock the doors with the key, the alarm is still armed because the key is not comunicating with the alarm just the cars factory keyless system.
